1 Introduction Maraging steels are ultra-high-strength alloys renowned for their exceptional combination of strength, toughness, and damage tolerance, making them ideal for demanding applications such as aerospace landing gear, rocket casings, and structural components [1-4]. Their strengthening arises primarily from precipitation of intermetallic phases (e.g., Ni3Ti, Ni3Mo) in a low-carbon martensitic matrix during controlled aging, following solution annealing [5-9].
